drm/amd/amdgpu: set MP1 state to UNLOAD before reload its FW for vega20/ALDEBARAN

When resume from gpu reset, need set MP1 state to UNLOAD before reload SMU
FW otherwise will cause following errors:
[  121.642772] [drm] reserve 0x400000 from 0x87fec00000 for PSP TMR [  123.801051] [drm] failed to load ucode id (24) [  123.801055] [drm] psp command (0x6) failed and response status is (0x0) [  123.801214] [drm:psp_load_smu_fw [amdgpu]] *ERROR* PSP load smu failed!
